+A new @code{output-attributes} grob property is now used for svg output
+instead of the @code{id} grob property.  It allows multiple attributes
+to be defined as an association list.  For example, @code{#'((id . 123)
+(class . foo) (data-whatever . @qq{bar}))} will produce the following
+group tag in an SVG file: @code{<g id=@qq{123} class=@qq{foo}

-A new page breaking function @code{ly:one-line-auto-height-breaking}
